Ball lightning 194422 225735202 2008-07-15T03:50:46Z RegenerateThis 7389666 {{Trivia|date=July 2008}} [[Image:Ball lightning appears cropped.jpg|right|382px|thumb|A photo purportedly depicting natural ball lightning. It was taken in 1987 by a student in [[Nagano]], [[Japan]].]] '''Ball lightning''' is an [[atmospheric]] phenomenon, the physical nature of which is still [[controversial]]. The term refers to reports of [[luminous]], usually [[spherical]] objects which vary from pea-sized to several meters in diameter. It is sometimes associated with [[thunderstorms]], but unlike [[lightning]] flashes, which last only a fraction of a second, ball lightning reportedly lasts many seconds. Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but it is presently unknown whether these are actually related to the naturally occurring phenomenon. Scientific data on natural ball lightning is scarce due to its infrequency and unpredictability. The presumption of its existence is based on reported public sightings, and have therefore produced somewhat inconsistent findings. Due to inconsistencies and the lack of reliable data, the true nature of ball lightning is still unknown.<ref name=bam>[http://www.abc.net.au/science/articles/2008/03/20/2194630.htm?site=science&topic=latest ABC.net.edu: ''Ball lightning bamboozles physicist'']</ref> Until recently, ball lightning was often regarded as a fantasy or a [[hoax]].<ref name="newscientist">{{cite web|url=http://www.newscientist.com/article.ns?id=dn1720|title=Ball lightning scientists remain in the dark|date=[[20 December]] [[2001]]|publisher=New Scientist}}</ref> Reports of the phenomenon were dismissed due to lack of physical evidence, and were often regarded the same way as [[UFO]] sightings.<ref name=bam /> Recently however, the overwhelming number of sightings has caused a renewed interest in studying the possible existence and nature of the phenomenon. Natural ball lightning appears infrequently and unpredictably, and is therefore rarely (if ever truly) photographed. However, several purported photos and videos exist. Perhaps the most famous story of ball lightning unfolded when 18th-century physicist [[Georg Wilhelm Richmann]] installed a [[lightning rod]] in his home and was struck in the head - and killed - by a "pale blue ball of fire."<ref name="economist">{{cite web|url=http://www.economist.com/science/displaystory.cfm?story_id=10918140|title=Great balls of fire!|date=[[27 March]] [[2008]]|publisher=''[[The Economist]]'' }}</ref> {{TOClimit|limit=2}} == Historical accounts == [[Image:Ball lightning.png|thumbnail|A 19th century depiction of ball lightning.]] A 1960 paper reported that 5% of the US population reported having witnessed ball lightning.<ref name="sciam-ask">{{cite web|url=http://www.sciam.com/askexpert_question.cfm?articleID=000CC3F9-66E4-1C71-9EB7809EC588F2D7&catID=3|publisher=Scientific American|title=Ask the experts|accessdate=2007-04-04}}</ref><ref>{{cite conference|first=J.

Four people died and approximately 60 were injured, when during a severe storm, an 8' ball of fire struck and entered the church, nearly destroying it. Large stones from the church walls were hurled into the ground and through large wooden beams. The ball of fire smashed the pews and many windows, and filled the church with a foul [[sulfur]]ous odor and dark, thick smoke. The ball of fire reportedly split in two, one exiting through a window by smashing it open, the other disappearing somewhere inside the church. The explanation at the time, because of the fire and sulfur smell, was that the ball of fire was "the devil" or the "flames of hell". Later, some blamed the entire incident on two people who had been playing cards in the pew during the sermon, whom they say must have invoked God's wrath. <ref>{{cite book|url=http://books.google.com/books?id=nBFJAAAAMAAJ&pg=PR8&dq=Wykes+Rothwell#PPR12,M1|title=Devon Notes and Queries|first=Peter Fabyan Sparke|last=Amery|coauthors=John S. Amery, Joshua Brooking Rowe}}</ref> ===Georg Richmann=== A report from [[1753]] depicts ball lightning as being lethal, when Professor [[Georg Richmann]] of [[Saint Petersburg]], [[Russia]], created a kite flying apparatus similar to the one built by [[Benjamin Franklin]] a year earlier. He was attending a meeting of the [[Academy of Sciences]] when he heard thunder, and ran home with his engraver to capture the event for posterity. While the experiment was underway, ball lightning appeared, collided with Richmann's forehead and killed him. The ball left a red spot on Richmann's forehead, his shoes were blown open, and parts of his clothes singed. His engraver was knocked unconscious. The doorframe of the room was split, and the door itself torn from its hinges.<ref>{{cite book|last=Clarke|first=Ronald W.|title=Benjamin Franklin, A Biography|publisher=Random House|year=1983|pages=87}}</ref><ref>"Frenchman Thomas Francois D'Alibard used a {{convert|50|ft|m|0|sing=on}} long vertical rod to draw down the "electric fluid" of the lightning in Paris on May 10, 1752. One week later, M. Delor repeated the experiment in Paris, followed in July by an Englishman, John Canton. But one unfortunate physicist did not fare so well. Georg Wilhelm Reichmann attempted to reproduce the experiment, according to Franklin's instructions, standing inside a room. A glowing ball of charge traveled down the string, jumped to his forehead and killed him instantly.[http://www.physicstoday.org/vol-59/iss-1/p42.html]</ref> ===Tsar Nicholas II=== [[Tsar Nicholas II]], the last Emperor of Russia, reported witnessing what he called "a fiery ball" while in the company of his grandfather, Tsar Alexander II: "Once my parents were away," recounted the Tsar, "and I was at the all-night vigil with my grandfather in the small church in Alexandria. During the service there was a powerful thunderstorm, streaks of lightning flashed one after the other, and it seemed as if the peals of thunder would shake even the church and the whole world to its foundations. Suddenly it became quite dark, a blast of wind from the open door blew out the flame of the candles which were lit in front of the iconostasis, there was a long clap of thunder, louder than before, and I suddenly saw a fiery ball flying from the window straight towards the head of the Emperor. The ball (it was of lightning) whirled around the floor, then passed the chandelier and flew out through the door into the park. My heart froze, I glanced at my grandfather - his face was completely calm. He crossed himself just as calmly as he had when the fiery ball had flown near us, and I felt that it was unseemly and not courageous to be frightened as I was....After the ball had passed through the whole church, and suddenly gone out through the door, I again looked at my grandfather. A faint smile was on his face, and he nodded his head at me. My panic disappeared, and from that time I had no more fear of storms." [http://www.orthodox.net/russiannm/nicholas-ii-tsar-martyr-and-his-family.html] ===Aleister Crowley=== British occultist [[Aleister Crowley]] also reported witnessing what he referred to as "globular electricity" during a thunderstorm on [[Lake Pasquaney]]<!-- no such place; perhaps Newfound Lake, which has a Camp Pasquaney --> in [[New Hampshire]] in 1916. As related in his Confessions, he was sheltered in a small cottage when he "noticed, with what I can only describe as calm amazement, that a dazzling globe of electric fire, apparently between six and twelve inches in diameter, was stationary about six inches below and to the right of my right knee. As I looked at it, it exploded with a sharp report quite impossible to confuse with the continuous turmoil of the lightning, thunder and hail, or that of the lashed water and smashed wood which was creating a pandemonium outside the cottage. I felt a very slight shock in the middle of my right hand, which was closer to the globe than any other part of my body.<ref name="AleisterCrowley">{{cite book|chapterurl=http://www.hermetic.com/crowley/confess/chapter83.html|first=Aleister|last=Crowley|title=The Confessions of Aleister Crowley: An Autobiography|chapter=Chp. 83|url=http://www.hermetic.com/crowley/confess/index.html|id=ISBN 0140191895|publisher=Penguin|date=[[1989-12-05]]}}</ref> ===Other accounts=== * On [[30 April]] [[1877]], a ball of lightning entered the [[Golden Temple]] at [[Amritsar]], [[India]], and exited through a side door. This event was observed by a number of people, and the incident is inscribed on the front wall of Darshani Deodhi.<ref>[http://www.sikhpoint.com/religion/sikhhistory/MainEvents/miracle.htm Anandpur Sahib Resolution<!-- Bot generated title -->]</ref> * Pilots in [[World War II]] described an unusual phenomenon for which ball lightning has been suggested as an explanation. The pilots saw small balls of light moving in strange trajectories, which came to be referred to as [[foo fighter]]s. * Submariners in WWII gave the most frequent and consistent accounts of small ball lightning in the confined submarine atmosphere. There are repeated accounts of inadvertent production of floating explosive balls when the battery banks were switched in/out, especially if mis-switched or when the highly inductive electrical motors were mis-connected or disconnected. An attempt later to duplicate those balls with a surplus submarine battery resulted in several failures and an explosion.<ref>[http://www.peter-thomson.co.uk/tornado/fusion/Ball_lightning_and_the_charge_sheath_vortex.html Ball lightning - and the charge sheath vortex<!-- Bot generated title -->]</ref> * On [[August 6]] [[1994]] a ball of lightning went through a closed window in [[Uppsala]], [[Sweden]], leaving a circular hole with a diameter of 5 centimeters. The incident was witnessed by residents in the area, and was recorded by a lightning strike tracking system<!-- This might be an incorrect translation of the word "blixtlokaliseringssystem" from the university article cited in the sources --> on the Division for Electricity and Lightning Research at Uppsala University.<ref>{{cite web|url=http://www.hvi.uu.se/Lightning/blixtar/Klotblixt.html|language=Swedish|publisher=Uppsala University|title=Ett fenomen som gäckar vetenskapen|first=Anders|last=Larsson|date=2002-04-23|accessdate=2007-11-19}}</ref><ref>{{cite web|url=http://www.dn.se/DNet/jsp/polopoly.jsp?d=537&a=179865&viewAll=true|publisher=Dagens Nyheter|language=Swedish|date=[[9 September]] [[2003]]|title=Finns det klotblixtar?|accessdate=2007-11-19}}</ref> == Inconsistent characteristics == Depending on the report, ball lightning can move upwards as well as downwards, sideways, or in odd trajectories such as rocking from side to side like a falling leaf. It can move with or against the wind, or simply hover, more or less stationary in the air. Sometimes it is described as being attracted to houses, cars, persons, or other objects, <ref>[http://www.ernmphotography.com/Pages/Ball_Lightning/BL_Info_10.html BL_Info_10<!-- Bot generated title -->]</ref> but sometimes the balls are reportedly repelled or are unaffected by objects. Some accounts claim the balls have passed freely through solid masses, such as wood or metal, without any effect on the ball or material, while other accounts report damage to the material, such as melting or burning. Some reports suggest an attraction to, or even an origination from electric power lines. <ref>[http://amasci.com/weird/unusual/blold2.html Unusual Phenomea Reports: Ball Lightning<!-- Bot generated title -->]</ref> Ball lightning has been reported in many different colors, sometimes even [[transparency (optics)|transparent]] or translucent. It is sometimes said to contain radial filaments or sparks while others are evenly lit, and some have flames protruding from the ball surface. Its shape has been described as spherical, oval, tear-drop, or rod-like. It has sometimes been reported during thunderstorms, sometimes issuing from a lightning flash, while sometimes it appears during calm weather with no storms in the vicinity. The balls have been reported to disperse in many different ways, such as suddenly vanishing, gradually dissipating, absorption into an object, "pop"ing, exploding loudly, or even exploding with force, which is sometimes reported as damaging. Some accounts say the balls are lethal, killing on contact, while other accounts claim that they are harmless. == Laboratory experiments == Scientists have long attempted to produce ball lightning in laboratory experiments. While some experiments have produced effects that are visually similar to reports of natural ball lightning, it has not yet been determined whether there is actually any correlation. [[Nikola Tesla]] reportedly was able to artificially produce ~1.5" balls, but he was really interested in higher voltages and powers, and remote transmission of power, so the balls he made were just a curiosity.<ref>Tesla, Nikola (1978). ''Nikola Tesla - Colorado Springs Notes 1899-1900''. Nolit (Beograd, Yugoslavia), 368-370. ISBN-13: 978-0913022269</ref> There is a scientific group that holds a regular symposium on ball lightning, called the "International Symposium on Ball Lightning" or ISBL: [http://home.wxs.nl/~icblsec/isbl99/reportantwerp.html 1999], [http://www.umsl.edu/~handelp/BLConference.html 2001], [http://home.planet.nl/~icblsec/noscript.html 2004 & 2006]. The next symposium will take place in [[Kaliningrad]], [[Russia]] in 2008.<ref>http://plasma.karelia.ru/events/info/isbl2008.doc</ref> A related group uses the generic name "Unconventional Plasmas".<ref>[http://home.planet.nl/~icblsec/frameset.html?pg_start.html ISBL'01 International Symposium on Ball Lightning<!-- Bot generated title -->]</ref> [[Image:Water plasma.jpg|200px|left|thumb|A demonstration of the water discharge experiment.]] ===Water discharge experiments=== Some scientific groups, including the [[Max Planck Institute]], have reportedly produced a ball lightning-type effect by discharging a high-voltage [[capacitor]] in a tank of water. <ref>[http://www.cosmosmagazine.com/node/334 'Ball lightning' created in German laboratory | COSMOS magazine<!-- Bot generated title -->]</ref><ref>http://www.jstage.jst.go.jp/article/pfr/1/0/039/_pdf</ref> ===Home microwave oven experiments=== Many modern experiments involve using a microwave oven to produce small rising glowing balls, often referred to as "plasma balls". It has not been proven that these balls actually consist of plasma, though. Generally, the experiments are conducted by placing a lit or recently extinguished match or other small object in an ordinary microwave oven. The burnt portion of the object flares up into a large ball of fire, while the plasma balls can be seen floating around the ceiling of the oven chamber. The balls can damage the oven, leaving burn marks. Some experiments describe covering the lit object with an inverted glass jar, which contains both the flame and the balls so they won't damage the chamber walls. Some experimenters have posted instructions, photos, and videos of these experiments.<ref>[http://jlnlabs.online.fr/plasma/gmr/index.htm How to make a Stable Plasmoid ( Ball Lightning ) with the GMR ( Graphite Microwave Resonator ) by Jean-Louis Naudin<!-- Bot generated title -->]</ref><ref>[http://www.angelfire.com/electronic/cwillis/microwave.html ball lightning in microwave ovens<!-- Bot generated title -->]</ref><ref>[http://www.powerlabs.org/uwavexp.htm#%A0%20Ball%20Lightning: POWERLABS's Microwave Experiments Page!<!-- Bot generated title -->]</ref> ===Silicon experiments=== Some more recent experiments in 2007 involve shocking [[silicon]] wafers with electricity, which vaporizes the silicon and induces [[oxidation]] in the vapors. The visual effect can be described as small glowing, sparkling orbs that roll around a surface. Two Brazilian scientists, [[Antonio Pavão]] and [[Gerson Paiva]] of the [[Federal University of Pernambuco]]<ref>[http://www.ufpe.br/ Universidade Federal de Pernambuco<!-- Bot generated title -->]</ref> have reportedly consistently made small long-lasting balls using this method.<ref>[http://www.ufpe.br/new/visualizar.php?id=5005 Pesquisadores da UFPE geram, em laboratório, fenômeno atmosférico conhecido como bolas luminosas<!-- Bot generated title -->]</ref><ref>[http://news.nationalgeographic.com/news/2007/01/070122-ball-lightning_2.html Ball Lightning Mystery Solved? Electrical Phenomenon Created in Lab<!-- Bot generated title -->]</ref> These experiments stemmed from the theory that ball lightning is actually oxidized silicon vapors ''(see [[#Vaporized silicon theory|vaporized silicon theory]], below)''. == Possible scientific explanations == An early attempt to explain ball lightning was recorded by [[Nikola Tesla]] in 1904,<ref>{{cite journal|last=Tesla|first=Nikola|authorlink=Nikola Tesla|url=http://web.archive.org/web/20051222121927/http://tfcbooks.com/tesla/wireless01.htm|title=The Transmission of Electrical Energy Without Wires|journal=Electrical World and Engineer|date=1904-03-05}}</ref> but currently, there is no widely accepted explanation of what exactly ball lightning is. Several theories have been advanced, however, since the phenomenon was brought into the scientific realm by the [[French Academy of Sciences|French Academy]] scientist [[François Arago]].{{Fact|date=January 2008}} === Vaporized silicon hypothesis === This hypothesis suggests that ball lightning consists of vaporized silicon burning through [[oxidation]]. When lightning strikes earth's silica-rich soil, the silicon could be instantly vaporized, the vapor itself condensing and burning slowly via the oxygen in the surrounding air. A recently published experimental investigation of this effect by evaporating pure silicon with an electric arc reported producing "luminous balls with lifetime in the order of seconds".<ref> {{cite journal |last=Paiva |first=Gerson Silva |coauthors=Antonio Carlos Pavão, Elder Alpes de Vasconcelos, Odim Mendes, Jr., Eronides Felisberto da Silva, Jr.|year= 2007|title= Production of Ball-Lightning-Like Luminous Balls by Electrical Discharges in Silicon|journal=Phys.

A surface discharge shorts these batteries, resulting in a current which forms the ball. His model is described as an aerosol, but not aerogel, model that explains all the observable properties and processes of ball lightning.<ref>{{cite journal |last=Meshcheryakov|first=Oleg |year= 2007|title=Ball Lightning–Aerosol Electrochemical Power Source or A Cloud of Batteries|journal=Nanoscale Res.

Inspired by M. Fitzgerald’s account of ball lightning on August 6, 1868, in [[Ireland]] that lasted 20 minutes and left a 6 meter square hole, a 90 meter long trench, a second trench 25 meters long, and a small cave in the [[peat bog]], Pace VanDevender, a plasma physicist at [[Sandia National Laboratories]] in [[Albuquerque, New Mexico]], and his team found depressions consistent with Fitzgerald’s report and inferred that the evidence is inconsistent with thermal (chemical or nuclear) and electrostatic effects. An electromagnetically levitated, compact mass of >20,000 kg would produce the reported effects but requires a density of > 2000 times the density of gold, which implies a mini black hole. He and his team found a second event in the peat-bog witness plate from 1982 and are currently trying to geolocate electromagnetic emission consistent with the hypothesis. His colleagues at the institute agreed that, crazy though the hypothesis seemed, it was worthy of their attention.<ref>{{cite journal|url=http://www.newscientist.com/channel/fundamentals/mg19225831.700-blackholes-in-your-backyard.html|journal=New Scientist|volume=192|issue=2583/2584|pages=48–51|title=Blackholes in your backyard|first=Hazel|last=Muir|date=[[23 December]] [[2006]]|doi=10.1016/S0262-4079(06)61459-0}}</ref> === Other hypotheses === There also are many other hypotheses put forth to explain ball lightning, such as: # Spinning electric [[dipole]] hypothesis. (Endean (1976) published this hypothesis. He postulated that ball lightning could be described as an [[electric field]] vector spinning in the [[microwave]] frequency region.) # [[Electrostatic]] Leyden jar models. (Singer (1971) discusses this type of hypothesis and suggested that the electrical recombination time would be too short for the ball lightning lifetimes often reported.) # J. Pace VanDevender separates extreme ball lightning of the highly energetic violent kind, and proposes a theory of [[neutrinos]] and heavy neutrinos. <ref>[http://www.thunderbolts.info/webnews/ieee_plasma_balllightening.htm The IEEE, Plasma Cosmology and Extreme Ball Lightning<!-- Bot generated title -->]</ref> # [[Nuclear reaction|Nuclear]] hypotheses # Trapped [[microwave]] hypotheses # [[Maser]] hypothesis # [[Fractal]] [[aerogel]] hypotheses (Smirnov (1987) put forward a charged aerosol cluster theory.) # [[Magnetism|Magnetically]] trapped [[Plasma (physics)|plasma]] theories # [[Vortex]] hypotheses (Coleman (2006) described ball lightning as a vortex fireball or natural vortex burning a [[combustible]] fuel. Ball lightning under this theory is essentially a turbulent swirling flame inside a vortex. # [[Rydberg matter]] hypotheses # [[Anti-matter]] hypotheses # [[Optical illusion]]s. == Esoteric explanations == Ball lightning has been connected to reports of several supernatural phenomena, ranging from [[will o' the wisp]]s to [[unidentified flying object|UFO]]s. Some people believe the ball lightning phenomena are [[ghost]]s or spirits, or are related to [[poltergeist]]s and [[spontaneous human combustion]].<ref name=newscientist/> References can be seen in the will o' the wisp and other spirits that take the guise of orbs of light. Some UFO [[Scientific skepticism|skeptics]] have suggested that many apparent [[close encounter]]s are actually observations of ball lightning. UFO enthusiasts report seeing ball lightning often at [[crop circle]] sites and believe them to be some kind of [[Intelligence (trait)|intelligence]] or come from some kind of intelligence while not denying that it is indeed ball lightning. == In popular culture == {{Trivia|date=July 2008}} [[Image:Tintin cover - The Seven Crystal Balls.jpg|thumb|A ball lightning, as depicted on the front cover of ''The Seven Crystal Balls'']] === Mythology === * Among the ancients of [[Japanese mythology]], there is a myth that ball lightning is the wrath of the thunder god, [[Raijin]]. * In [[Basque mythology]] ball lightning were believed to be either main deity, [[Mari (goddess)|Mari]] or [[Sugaar]], traveling from one mountain to another. * M. l'abbé de Tressan, in ''Mythology compared with history: or, the fables of the ancients elucidated from historical records'': <blockquote> ...during a storm which endangered the ship [[Argo]], fires were seen to play round the heads of the [[Tyndarides]], and the instant after the storm ceased. From that time, those fires which frequently appear on the surface of the ocean were called the fire of [[Castor (mythology)|Castor]] and [[Pollux (mythology)|Pollux]]. When two were seen at the same time, it announced the return of calm, when only one, it was the presage of a dreadful storm. This species of fire is frequently seen by sailors, and is a species of ''[[ignis fatuus]]''. (page 417) </blockquote> * In Filipino folklore, a creature called [[St. Elmo's Fire|santilmo]] in the Visayas Regions is described with high similarity to a ball lightning. === Literature === An early fictional reference to ball lightning appears in a children's book set in the 1800s by [[Laura Ingalls Wilder]].<ref>{{cite book|first=Laura Ingalls|last=Wilder|authorlink=Laura Ingalls Wilder|title=On the Banks of Plum Creek|publisher=Harper Trophy|year=1937}}</ref> The books are considered historical fiction, but the author always insisted they were descriptive of actual events in her life. In Wilder's description, three separate balls of lightning appear during a winter blizzard near a cast iron stove in the family's kitchen.

The character who is thus empowered plays a benevolent role, and recurs in several stories with plots including search for [[El Dorado]], and alien encounters. === Film === * In the Russian film ''[[Burnt by the Sun|Burnt by the Sun (1994)]]'' a crackling lightning ball appears at several key moments throughout the picture. It passes through rooms, sometimes causing damages, like cracking the glass covering family photographs at the end of the feature. At one point, it explodes in the forest, setting a tree on fire. * In the [[anime]] series [[Princess Nine]], female pitcher Ryo Hayakawa has a high speed fastball called the 'lightning ball'.
